Mixed Connective Tissue Disease: Types, Diagnosis, Symptoms
About MCTD, an Autoimmune Connective Tissue Disease
Learn about MCTD, an autoimmune connective tissue disease. This disease affects the skin, subcutaneous tissue, muscle, bone, and lungs. While it is a rare condition in children, it can lead to serious complications, such as lungs disease. Find out what causes this condition and how you can prevent it. Then, read on to learn more about the symptoms and treatment options. To learn more about MCTD, read the rest of this article.
MCTD is a type of autoimmune connective tissue disease
MCTD is a constellation of rheumatic diseases with an inflammatory component. Among these conditions are systemic lupus erythematosus, polymyositis, scleroderma, and rheumatoid arthritis. In addition to these rheumatic diseases, MCTD can also involve biochemically abnormal connective tissue, such as in cases of Ehlers-Danlos syndrome or Marfan syndrome.
In thirty to forty percent of patients, the white blood cell count falls too low. Additionally, there are abnormalities in the lymph nodes, spleen, and liver. The disease can be refractory or enter spontaneous sustained remission in up to 40% of cases. Treatment for MCTD depends on the severity of the disease, the organs involved, and the patient's age at diagnosis.
Symptoms of MCTD may range from mild to life-threatening. Patients with the condition may experience swollen fingers and joints, as well as Raynaud's phenomenon and scleroderma, two other connective tissue diseases with similar symptoms. In addition to inflammatory symptoms, MCTD may be accompanied by a rash, or may cause an unusual increase in temperature.
MCTD is a rare type of inflammatory rheumatic disease with symptoms similar to those of scleroderma, dermatomyositis, and lupus. Antibodies to the nuclear proteins of these disease trigger the immune system to attack body tissues, causing inflammation and damage. This condition is also very painful, and some patients develop symptoms of rheumatoid arthritis.
While MCTD is not curable, treatment options are available. A good approach is to work with your healthcare provider, and seek treatment as soon as symptoms become worse. In addition to seeking medical attention, understanding triggers and managing your symptoms can help you live a healthy life with MCTD. This type of autoimmune connective tissue disease requires regular visits to a healthcare provider. The right treatment can help you avoid flares and maintain a quality of life.
It affects the skin, subcutaneous tissue, muscle, and bone
Many parts of the body are supported by connective tissue. It acts as "cellular glue" and gives body parts shape. The connective tissue supports and strengthens all of the other parts of the body. The connective tissue is composed of many different types of proteins, including collagen. The tissue makes up skin, muscle, bone, and cartilage. Diseases of the connective tissues may lead to pain, swelling, and even scarring.
Symptoms of connective tissue disease may affect the skin, subcutaneous tissue, muscle, or bone. US is a useful tool to detect disease-related changes in the skin and subcutaneous tissue. Because tissue thickness varies with age and body site, the US must be done on a control site to determine the exact extent of the lesions. Active lesions will have increased echogenicity and blood flow, as well as loss of subcutaneous fat. US findings can corroborate with clinical examination.
A diagnosis of connective tissue disease is important because symptoms may mimic other illnesses. In order to confirm the diagnosis and rule out other causes, your doctor will likely perform a series of diagnostic tests. These tests may include an MRI of your brain, spinal tap, or lumbar puncture. If your doctor suspects an underlying disease, a chest x-ray may be ordered to look for any signs of inflammation in your lungs. Other tests may include an electromyogram to record nerve signals. A biopsy of the nerve may also be ordered to confirm the diagnosis.
Some people may also develop symptoms of scleroderma. Morphoderma affects the skin over the joints. It can limit growth and mobility and result in contractures and long-term disability. Patients suffering from this disorder should seek treatment immediately. In some cases, morphea symptoms can be treated by their primary care physician and a dermatologist. However, treatment for scleroderma may require a referral to a rheumatologist.
It is a rare disease in children
One of the most common causes of arthritis is a faulty immune system. People who suffer from autoimmune diseases, such as arthritis, may have symptoms of different types of connective tissue disease. While the condition is a relatively rare disease in children, it is more common in girls than in boys. MCTD is characterized by antibodies that are produced by the immune system against the body's tissues. Eventually, this can lead to the inflammation and destruction of the body's tissues.
While juvenile systemic sclerosis is most often characterized by skin changes, it can also affect the elbow, wrists, and knees. In some cases, it can progress to the point of congestive heart failure. Girls are more likely than boys to develop JSS, but there is no racial predilection. Although the symptoms of juvenile systemic sclerosis are not the same in boys and girls, they are indicative of the underlying condition.
A genetic disorder called Marfan syndrome is one of the most common forms of connective tissue disease. In this condition, the body lacks the protein fibrillin. The result is weaker connective tissues and multiple dislocations. People with Marfan syndrome also have flat feet and double-jointedness. In some cases, the condition may also be associated with spinal deformities, hernias, and rheumatic fever.
In the event that a child develops a connective tissue disease, diagnosis is made by a medical doctor. The disease is characterized by inflammation of the skin and organs. The symptoms of the disorder include rash on the cheeks and mouth, pain and tenderness, and fluid on the heart. Patients may also experience fatigue and loss of appetite. Some patients may also experience fever and fatigue.
It can lead to complications with the lungs
If left untreated, connective tissue diseases can be dangerous, leading to pulmonary problems. However, there are treatments for this condition, including medications, vitamin supplements, and physical therapy. Diagnosis of connective tissue diseases can be difficult, as symptoms can mimic other conditions. Your physician will likely perform diagnostic tests to rule out other causes and confirm your diagnosis. Your doctor may also order tests to determine the severity of your condition, including chest x-rays to look for inflammation in your lungs. Lastly, a nerve biopsy may be performed to confirm the diagnosis.
Several academic medical centers have begun to develop multidisciplinary CTD-ILD clinics, which involve respiratory specialists and rheumatologists to treat patients with connective tissue disease. The clinic at Brigham and Women's Hospital in Boston has been successful, with over 50% of patients whose initial diagnosis was IPF being switched to CTD-ILD. However, the disease is far more complex than that.
Patients with connective tissue disease are prone to developing interstitial pulmonary diseases. Interstitial pulmonary disease affects the airways, pulmonary vasculature, and structures of the chest wall. Patients with multi-compartment involvement of these areas may develop lung infections or pulmonary hypertension. Some of these patients may also develop vasculitis alongside intercompartmental involvement.
The symptoms of connective tissue disease include cough, chest pain, and fever. These patients may also be taking immunosuppressive drugs. Treatment for connective tissue disease is dependent on the severity of the condition. A few tests can help differentiate between the two main diagnoses, including HRCT and BAL lymphocytosis. If you suspect CTD, make sure to consult your doctor as soon as possible.
It is treated with immune treatments
In general, newer stem cell treatments for connective tissue disease help reduce disease activity and inflammation. The immune system "burns out" with age, so a person with UCTD can generally survive for 10 years or longer after diagnosis. The prognosis varies, however, from patient to patient. In some cases, the prognosis is even worse than the individual connective tissue disease. To learn more about the various immune treatments for UCTD, read on.
One type of connective tissue disease is lupus erythematosus. Another type is mixed connective tissue disease. ANA antibodies indicate a misidentification by the immune system. Although ANA antibodies are found in the blood of people with UCTD, many others have low levels of the antibodies, which doesn't necessarily mean they have the disease. Other ANA antibodies associated with defined connective tissue diseases are anti-double-stranded DNA (anti-DNA) antibodies, anti-Ro/SSA, anti-La/SSB, and anti-RNP. These antibodies can also be associated with rheumatoid factor, and some types of arthritis.
Some connective tissue disorders are inherited. For example, Marfan syndrome is a disorder of elastin, while Ehlers-Danlos syndrome is an inherited connective tissue disease. In addition, some individuals who are born with this disorder may never develop a fully defined connective tissue disease. However, if this is the case, a patient can eventually progress to a classic form.
Newer therapies are available for connective tissue diseases. Some suppress the immune system, while others work to improve the overall condition. Medications for rheumatoid arthritis are immunosuppressives that help to control the inflammation. For milder cases, antimalarial drugs can prevent flare-ups. Methotrexate is another drug used for rheumatoid arthritis. Some medicines for pulmonary hypertension help to open up blood vessels.
